[0054] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0055] Please refer to Figures 1-6 , the present application provides the following technical solutions:

[0056] A multi-station sawing system includes a sawing unit 1, a control unit 2, and a hydraulic unit 3. The sawing unit 1 is used to saw a workpiece 100; the control unit 2 is electrically connected to the sawing unit 1 to form a control and feedback loop; the hydraulic unit 3 is connected to the sawing unit 1 and is used to provide hydraulic power for the components of the sawing unit 1. The specific connection form of the above three units can adopt the existing technology, and this content is not the key point of this solution and will not be elaborated here.

[0057] This solution mainly improves the sawing unit 1, which includes three sawing units, each of which is connected to the control unit 2 and the hydraulic unit 3. Each cutting unit includes a cutting part 12, which is used to cut the workpiece 100; the cutting part 12 includes two cutting members 121 arranged in parallel. The cutting member 121 is a cutting tool, the movement direction of the cutting member 121 is the vertical direction, and the feeding direction of the workpiece 100 to be cut is the horizontal direction; there is a gap between the two cutting members 121.

[0058] The cutting member 121 can be adapted with existing cutting components, such as belt cutting, wire cutting, and saw blade cutting, as long as the movement direction of the cutting member 121 itself is vertical.

[0059] The cutting unit further includes a positioning portion 11 and a frame 13 . The positioning portion 11 is used for positioning and conveying the workpiece 100 ; and the frame 13 is used for carrying the positioning portion 11 and the cutting portion 12 .

[0060] Through the structure of this solution, combined with two parallel cutting pieces 121, a cutting path corresponding to the workpiece groove 101 on the workpiece 100 is formed, and the one-time cutting of the two side walls of the workpiece groove 101 can be directly completed, which greatly improves the cutting efficiency. If multiple cutting units are set, they can be operated synchronously according to needs, and multiple cutting units perform the same or different cutting actions, shortening the time required for the entire workpiece processing.

[0061] On the basis of the above embodiment, the frame 13 includes a cutting frame 131 for supporting the cutting part 12, and a material channel is provided on the cutting frame 131 corresponding to the positioning part 11. A bottom frame 132 is provided on one side of the bottom of the cutting frame 131, and the bottom frame 132 is a pool-shaped structure; a positioning frame 133 is provided in the pool-shaped structure inside the bottom frame 132, and the positioning part 11 is provided on the positioning frame 133.

[0062] Through this structure, the bottom frame 132 can be used to receive the debris generated by cutting. The bottom of the bottom frame 132 is a double-layer plate structure, with a space between the upper plate and the lower plate, a material collection port is opened on the upper plate, and an exhaust pipe and a filter screen can be set in the bottom frame 132.

[0063] Based on the above implementation scheme, see Figure 4 and Figure 5 The positioning part 11 includes a clamping mechanism 111 and a conveying mechanism 112. The clamping mechanism 111 is used to clamp the workpiece 100 to be cut; the conveying mechanism 112 is linked with the clamping mechanism 111 to drive the clamping mechanism 111 to move toward or away from the cutting piece 121.

[0064] The clamping mechanism 111 includes a clamping block group, which is composed of a first clamping block 1111 and a second clamping block 1112. A clamping space for the part of the workpiece 100 to be cut is formed between the first clamping block 1111 and the second clamping block 1112. The first clamping block 1111 and the second clamping block 1112 can approach or move away from each other, and they move synchronously during the process of approaching or moving away from each other.

[0065] A placement groove is provided on the side of the first clamping block 1111 facing the second clamping block 1112, and the shape of the placement groove corresponds to the cutting part of the workpiece 100. As Figure 5 shown, since an end position of the workpiece 100 needs to be cut, the placement groove on the first clamping block 1111 includes a rectangular groove and a circular groove. The circular groove is close to the cutting piece 121, the rectangular groove is communicated with the circular groove, and one end of the rectangular groove away from the circular groove is an open end. With this structure, the workpiece 100 can be clamped inside the first clamping block 1111.

[0066] For the convenience of cutting, a gap is left between the outer side of the second clamping block 1112 facing the cutting piece 121 and the outer side of the first clamping block 1111 facing the cutting piece 121. If the second clamping block 1112 and the first clamping block 1111 are flush, it will instead increase the debugging difficulty of the equipment, that is, the adjustment difficulty of the position between the cutting piece 121 and the clamping block group. Through the setting of the structure of this solution, in addition to the equipment debugging being simpler, the notch area formed between the end sides of the first clamping block 1111 and the second clamping block 1112 is also easier for the staff to observe.

[0067] As a further optimized setting, sensors such as a contact switch, a proximity switch, a Hall sensor, etc. can be provided on the end side of the second clamping block 1112 facing the cutting piece 121, which are used to detect the movement track of the cutting part 12, and detect whether the cutting piece 121 has cut in place through the sensors, so as to improve the automation and controllability of the device.

[0068] On the basis of the above implementation scheme, the conveying mechanism 112 includes a conveying driving part 1121, and the conveying driving part 1121 is a cylinder, and its cylinder body is fixedly arranged on the positioning frame 133. The piston end of the conveying driving part 1121 is fixedly connected to the conveying frame 1122, and the clamping mechanism 111 is arranged on the conveying frame 1122. The lower part of the conveying frame 1122 is slidably connected to the positioning frame 133.

[0069] Two feeding slide rails are arranged on the upper part of the positioning frame 133, the length direction of the feeding slide rails is parallel to the movement direction of the conveying driving part 1121, and sliders corresponding to the feeding slide rails are arranged on the lower side of the positioning frame 133.

[0070] The positioning part 11 further includes a positioning driving assembly 113. The positioning driving assembly 113 is linked with the first clamping block 1111 and the second clamping block 1112. The positioning driving assembly 113 includes a positioning driving member 1131 and a positioning linkage member. The positioning driving member 1131 is a cylinder. The movable end of the positioning driving member 1131 is connected to the second clamping block 1112. The cylinder body of the positioning driving member 1131 is fixedly connected to the conveying frame 1122. The positioning linkage member includes two parallel racks and a gear. The gear is arranged between the two racks, and the two racks are respectively fixedly connected to the first clamping block 1111 and the second clamping block 1112. The gear is rotatably arranged on the conveying frame 1122. A transverse sliding rail is further arranged on the conveying frame 1122. The transverse sliding rail is a rod-shaped structure, and its length direction is parallel to the clamping direction of the clamping block group. The first clamping block 1111 and the second clamping block 1112 are slidably connected to the transverse sliding rail.

[0071] With this structure, the synchronous movement of the first clamping block 1111 and the second clamping block 1112 can be realized. Since the dual cutting member combination structure is adopted in this solution, the centering position of the workpiece 100 is particularly important. If only a clamping structure with a single clamping block movement is adopted, the cutting position may deviate after long-term operation. And the positioning linkage member of this solution is more conducive to the positioning of the workpiece 100 corresponding to the two cutting members 121.

[0072] On the basis of the above implementation, see Figure 6 , the cutting part 12 further includes a cutting positioning member 122. The cutting positioning member 122 is fixedly arranged at the upper and lower parts of the material channel of the cutting frame 131, and one cutting positioning member 122 is provided corresponding to each cutting member 121.

[0073] Each cutting positioning member 122 includes a cutting positioning seat 1221. The cutting positioning seat 1221 is fixedly connected to the cutting frame 131. A first positioning block 1222 and a second positioning block 1223 are respectively arranged on the cutting positioning seat 1221. The first positioning block 1222 and the second positioning block 1223 are arranged in an up-and-down structure. The second positioning block 1223 is arranged below the first positioning block 1222. Both of them are slidably connected to the cutting positioning seat 1221. Locking members are respectively arranged between the first positioning block 1222 and the second positioning block 1223 and the cutting positioning seat 1221.

[0074] The first positioning block 1222 and the second positioning block 1223 are both provided with positioning grooves corresponding to the cutting member 121 on the side facing the cutting member 121. The positioning grooves are in a "convex" shape structure. One of the cutting members 121 is located in the positioning groove of the first positioning block 1222. And the outer wall of the second positioning block 1223 is in contact with the outer wall of the cutting member 121.

[0075] To Figure 4The directions shown are for illustration purposes. There are two cutting positioning members 122 provided in the material passage of the cutting frame 131, which are respectively located at the upper and lower edges of the material passage. The upper cutting positioning member 122 corresponds to the left cutting member 121, and the lower cutting positioning member 122 corresponds to the right cutting member 121. Combining Figure 4 and Figure 6 , taking the upper cutting positioning member 122 as an example, the positioning groove of its first positioning block 1222 passes through the left cutting member 121 inside, and the left outer wall of the second positioning block 1223 is in contact with the side surface of the cutting member 121. The right cutting member 121 passes through the inside of the positioning groove of the second positioning block 1223, and the right outer wall of the first positioning block 1221 is in contact with the outer side surface of the right cutting member 121.

[0076] The cutting positioning member 122 with this structure can well position the cutting member 121 to ensure the stable position of the cutting member 121 during the cutting process.
